Great hand made cups , keeps coffee warm quire a while

Great size, and very stylish. Double walled insulation stops hands burning. Great product.

Not sure about these 250ml double walled glass coffee mugs which arrive in a plain white cardboard box. They look okay - but they do appear to be very thin glass and there's nothing to suggest that they're made from food grade borosilicate glass, as is often the case with this type of glass mug and denotes a degree of toughness.Alarm bells ring for me when looking at aspects of the online listing. The heading suggests these mugs are dishwasher safe but lower down in the body of the listing, it's recommended they be washed 'slowly with a cloth by hand'. The lack of consistency - even just in the description - bothers me.Particularly concerning are the online instructions to 'not rinse the (safety) hole directly or soak the cup in water for a long time, and do not wipe the safety hole forcefully'. This all suggests a delicacy that means I'd be reluctant to use these glass mugs on a daily basis as I suspect they'd be a little tricky to maintain - which is far from ideal - and may even be so fragile they'd be prone to breakage and not so durable.

Everything in the description on the listing is true, these cups are ever so light, and really easy to hold.Being double walled the outside does not get hot at all.Have been using these outside for the last week and one surprise was how long they stay warm.And they also look very nice and modern

These are very lightweight and thin which feels more like plastic. I would be embarrassed to serve coffee in these mugs to guests. I have returned for a refund and will have to go into a shop where I can pick up before buying.

Upon delivery one of the mugs handles were chipped, then while drinking coffee out of one of them a few days later it cracked and a small piece of glass broke off into the thermal part of the mug. I was so scared incase I had swallowed it by accident. But eventually saw it in the coffee at the bottom. Not happy at all they are expensive and don't last long at all.

I just put oats and cold milk and the glass brakes

I love double wall glass mugs. They keep the coffee warm longer—not like an insulated cup—but that’s not what I wanted. These are a replacement for some I had broken. They do break more easily than a ceramic mug.

We really enjoy using these. Easy to clean by hand or in the dishwasher. With it being glad you worry but it’s actually thin but sturdy. Four is the perfect amount of them. Highly suggest to add to you collection.

I love these cups so much! They are far better than even described! They are as light as China, but durable and dishwasher safe. I wish I had been using these cups always, they are that enjoyable! I highly recommend these cups. They are light as a feather!

They are a little smaller than I needed. I will had to drink less coffee.

Gift for my daughter. Right size, clear glass, insulated & good price.
